Remove the outer "leaves" from the lemongrass and put the soft inside aside. Cut the rest into small pieces. Boil 250 ml water with lemongrass, stir in stock, simmer for 5 minutes, stir in vinegar.
Season with chilli spice and sugar. Peel garlic and dice finely. Put aside lemon grass and chop very finely. Remove the seeds from the chilli, wash and cut into strips. Leek onions clean, wash and in rings cut.
Heat the oil in a frying pan and fry the minced meat for about 5 minutes until coarsely crumbly. Add garlic, chilli and lemongrass for the last 2 minutes and fry. Season strongly with salt and pepper. Remove from heat and mix in spring onions.
Pour the lemongrass vinaigrette through a sieve, mix everything, let it cool down. Quarter the pineapple and cut out the stalk. Peel quarter and cut into pieces. Clean and wash the salad, pluck into small pieces and drain.
Wash parsley, dab dry and cut into strips. Coarsely chop the peanuts. Mix pineapple, parsley and salad into the mince. Season to taste again. Serve sprinkled with peanuts.
